How can for a while toddler bird die?

my bird just died and i dont know how so i wanted to know how many things that can take place to a baby bird
toddler birds are extremely hard for people to look after even if they are the slightest bit cold hungry thirsty or sick could kill in cold blood them even a shock or something,
Let's see here... You could step on a bird and squish it to death. You could strangle it. You could talk it to destruction. Poison is also probably very effective. You could shove a tube down its mouth and pump a few gallons of Everclear down its throat. You could use it as a baseball in suitcase you lost your ball over the neighbor's fence. You could use it as fish bait the next time you have a feeling like going fishing. I bet birds would make a pretty good fist-sized chamois within case you need to wash your vehicle. I wouldn't be surprised if other birds liked the taste of newborn bird, so you could use it as food for the next bird you'll inevitably be too irresponsible to keep alive. There are endless scenario here, and I've just pecked the surface. You should be more careful the next time somebody entrusts you next to the life of what should have been a really nice little pet. Shame on you.
Answers:    There are lots of things that can go wrong with a newborn bird. Maybe yours wasn't getting the diet he needed or wasn't warm enough. Or it could be, as the other person said, he be just born sick.
It probably was born sick
I purely adopt a nanday conure. What does within propose when she puffs her feathers on her lead and nouns and bobs?   Medication for a parakeet that can't poop?   What to nurture my hens?   What would be the probability of me getting a Yellow Headed Amazon impersonator contained by Brisbane, QLD?
